Guhring 9024640064000 Jobber Drill Bit 6.4mm Carbide

Product Description

The GUHRING 9024640064000 is a jobber-length drill bit designed for precision drilling in aluminum and other non-ferrous materials. Built from solid carbide grade K40 and finished with a FIREX coating, it delivers consistent performance in high-wear applications. The bit features a 118-degree faceted point angle with web thinning for easier entry and reduced thrust. At 6.4 mm in diameter with a 3.98-inch overall length, it fits standard jobber-length workflows on CNC machining centers and manual drill presses. Licensed machinists and tool-and-die professionals are the primary installers.

This drill bit is suited for production and job-shop environments where aluminum, brass, copper, and similar non-ferrous workpiece materials are regularly machined. The FIREX coating reduces friction and built-up edge on soft metals, extending tool life between regrinds. The straight-cylindrical shank seats in standard drill chucks and collets without modification. The 5xD flute-to-diameter ratio supports chip evacuation in deeper passes up to a maximum drilling depth of 2.10 inches (53.40 mm).

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance in non-ferrous cutting
• FIREX coating reduces friction and heat buildup on aluminum and soft metals
• 118-degree faceted point with web thinning for reduced entry thrust
• Right-hand spiral flute promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and ER collets
• DIN specification conformance for consistent dimensional tolerances

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard drill chucks and collet systems accepting a 6.4 mm straight-cylindrical shank; rated for aluminum and non-ferrous workpiece materials per Series 2464 specification.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel. Secure the shank fully in a properly sized collet or drill chuck before operation, and verify runout before beginning a production run. Do not exceed the recommended maximum drilling depth of 53.40 mm without retracting to clear chips. Always power down the spindle completely before changing tooling.
